Application filed October 19, 1905. Serial No, 288,!66.

draw ngs, isa specification, like letters on the drawings. representinglike ps' Myinvention aims to improve welt beating machines for beatingout a welt after it has beenapplied to an upper and before the sole islaid or applied, in order to flatten-the welt and cause it to projectsubst ntially in or parallel with the planeof the sole.

Referring to the -drawings,Figure 1 is a vertical sectiontaken onthe-line a-a, Fig.

2--of a machine selected for illustration of the invention herein; Fig.2 is a rear elevation, and Fig. 3 a top or plan view of the front rtionof said machine.

is made in anv suitable or desired shape, it comprising as herein showna base 2, ads ted to be secured to a bench or column, a f ront wall 3,and side walls 4. The front wall curves outwardly and upwardly towardthe top and is shaped to form a solid anvil or, welt support 5 havingaflat horizontal surface 6 for receiving the welt. Said anvil haspreferably a straight or nearly straight front edge with tapering orslanting sides leading thereto forming a. .narrow front portion adaptedto facilitate easy handling of the shoe in beating, and particularlytofacilitate the entrance of said support into the" crease of a shoe so asto enable substantially the enmounted upon the upper arm of the lever 19tire width of the welt to beacted u n. I

Just back oi'the welt support t e frame has a horizontal pivotnin 11uponwhich'is pivotally mounteda Hammeror welt beater faces of the beaterand they welt. sup

7, formed as a bell, crank lever having its horizontal arm 8 extendedforward and shaped'to form ahammer or heater head 9 in juxtaposition andfor cooperation with the welt support 5. The beating face of the beateris shown'as fiat-and has a straight or nearly straight. front edge withtapering sides similar'to thatof the welt support, in order to effectasuitable flattening of the welt interposed between the cooperating rt.The otherand upright arm "160i the beater is pivotally connected to aneccentric 20 mounted on the drive shaft 12, the latter 0 In t heinvention as illustrated the frame 1- having fast and loose pulle s 13and 14 (see Fig. 1) controlled by a suita e belt shifter 15.

Instead of mounting the drive shaft in a fixed frame, as is-usual, it isin accordance with' my invention joumalcd in movable bearings 17 carriedbyandpreferably intogrally formed upon {the forked'arrns 18 of an. or"vertical lever 19. Extending transversely from this lever and in thevertical plane of'the forked arms 18 are tubular fulcrum bearings21, toreceive a pivot or fulcrum pin 22 supported in the'side' walls'of thismanner it may be swung back and forth toward the welt support by theadjusting means now to be described to var the, limits of the stroke'r-oscillation of the eater.

' the frame. By mounting the drive shaft in The lower arm 23 of thelever 19 is ivotally connected at 25 to the bifurcate head 24 of anadjusting rod 30. This rod is'eie tended forward through the front wall3 of the frame and at its front end is threaded to receive the tensionnut 26.- This nut 26 is seated upon an adjusting or seat screw 27 tappedinto the frame and through which the adjusting rod slides freely. Atension, s ring 28 is mounted on the rod 30 between t e head 24 and theseat screw 27, the tension of the spring tending to force the lower endof the lever 23 toward the rear (see Fig.

1) until the tension nut 26 is seated u n thehead of the seat screw 27,when furt ier motion in that direction is arrested. The rod 30 and thelower arm 23 of the lever 19 are movable toward the front of the machineupon compression of the tension spring 28,

this arrangement permitting the shaft '12 to swing rearwardly when theheater in its downward stroke contacts with an interposed welt, thusproviding am le yield of the heater to cushion the effect 0 its blowsupon the welt. By turning thev adjusting Or seat screw 27, the rod 30 ismoved in either'direetion, as desired, but without va ing the springtension, thus tomove the driveshaft .12 toward or from the welt supportand vary the position-0f the are through which'the beater headoscillates, or in other words, to vary the approach of the heater toaudits recession from the welt support. The-distance or interval betweenthewelt support and the. beater head-istlms madeadjustable toaccommodate any thickness of welt; while inany, desired adjustment thetension 1 of the beater are manner tocoincide wlth the resultant forceof the of the spring and the varied by turning the beater blows may betension nut 26.

By providing an oscillating beater where the beating surfaces 0 en andclose like a pair of jaws, the angu ar opening between the beatingsurfaces is especially adapted to receive the shoe-attached welt, whichbefore it is beaten down naturally conforms tp or fits into the saidangular opening, the nip or bend of the welt next the upper or inscamoverlying the front edge portion of the support and in the widest partof the angular opening, while the edge portions lie nearer to the vertexof the said opening. The blows thus more evenly distributed over thesurface of the welt than is possible with machines employingreciprocating bieaters and the nip .or bend of the welt is not beatenany more than is necessary to roduce the desired result. The beating isd one only where it is most needed and without straining or breaking theseams, the quality and durability of the welt being unimpairec Tooperate the machine the belt is shifted to the fixed pulley rotating thedrive shaft and eccentric to produce rapid oscillations of the beater. Ashoe 31, shown-in dotted lines in Fig. 1, is then brought into positionwith the bottom of the crease against the edge of the welt support, thewelt 32 attached to the up er over ying the face of the welt sup ort were it Wlll receive the rapid blows of t e beater and be flattened outupon the support and thereby made to lie flat or straight out from theupper in proper position to receive the" outer sole. The shoe is thenturned gradually to cause all sections of the welt to pass over the weltsupport till the whole welt has been flattened out in this plane of theinsole. v

In the usual ad'ustment of the machine the beater is oscilfated so thatit does not strike the welt support, the clearance, which is adjustable,corresponding to the thickness of the welt used.
